L represents a divalent linking group, and when a plurality of L is present, L's may be the same or different,
M represents a hydrogen atom or a counteraction, and when a plurality of M is present, M's may be the same or different, and
n represents the number of 1 to 4, and m represents the number of 0 to 3, provided that m+n is 4:
wherein R 101 , R 102 and R 103 each independently represent a monovalent substituent,
R 104 and R 105 each independently represent a hydrogen atom or a monovalent substituent, and
n 101 and n 102 each independently represent the number of 0 to 5, and n 103 represents 0 to 4, and when n 101 , n 102 and n 103 each represent the number of 2 or more, each of pluralities of R 101 , R 102 and R 103 may be the same or different.
2. The coloring composition according to claim 1 ,

wherein n101, n102, n201 n202 each independently represent the number of 2 to 4.
6. The coloring composition according to claim 1 ,
wherein n103 and n203 represent 0.
7. The coloring composition according to claim 1 ,
wherein M is a lithium ion, a sodium ion or a potassium ion.
8. The coloring composition according to claim 1 ,
wherein the compound represented by Formula (1) is contained in an amount of 1% by mass to 20% by mass.
9. An ink for inkjet recording comprising the coloring composition according to claim 1 .
10. An inkjet recording method comprising forming an image by using the coloring composition according to claim 1 .
11. An inkjet recording method comprising forming an image by using the ink for inkjet recording according to claim 9 .
12. A compound represented by Formula (1):
